gt can you please explain the nigger prank how can you provide input for a captcha sort of often with captchas at the time there are two words shown one easy and one blury and hard to read from a book or other source the easy one is used to verify youre human and then the other answer is stored away if enough humans answer the same for the second answer you trust that answer so the idea was youd always answer correct for the easy word then nigger for the second word and therefore poison the results trolls thought they were genius but the engineers just added a line of code like if other answer nigger multiply by a small probability thats true because it is unlikely to be true
